2 Απρ 2024 · Using a pre-made Ultralox40 Hypochlorous Acid (HOCl) solution for water disinfection offers a straightforward and flexible approach, particularly suited for smaller operations or facilities with limited space for additional equipment.
4 Νοε 2021 · Point-of-use [POU] drinking water treatment systems do not require distribution networks and therefore negate the need to maintain residual chlorine levels. The World Health Organization...
Hypochlorous acid and other chlorine compounds having disinfecting ability by virtue of their being oxidizing agents will oxidize sulfites (SO 3 2-), sulfides (S-), and ferrous (Fe 2+) or manganous (Mn 2+) ions. The disinfecting species are reduced, and the products have no disinfecting activity.
Chlorine, whether in the form of chlorine gas from a cylinder, sodium hypochlorite or calcium hypochlorite, dissolves in water to form hypochlorous acid (HOCl) and hypochlorite ion (OCl−). Chlorination can be achieved by using liquefied chlorine gas, sodium hypochlorite solution or calcium hypochlorite granules and on-site chlorine generators.
What is Hypochlorous Acid (HOCl)? Hypochlorous acid is a weak acid that is produced by electrolysis, a process that includes only water, salt, and electricity. HOCl is a potent oxidising agent that is widely used for disinfection due to its effectiveness against a broad spectrum of pathogens, including bacteria, viruses, fungi, and yeasts [1].
27 Νοε 2016 · In order to combat waterborne diseases, different disinfection methods are used to inactivate pathogens. Along with other water treatment processes such as coagulation, sedimentation, and filtration, chlorination creates water that is safe for public consumption. Chlorination is one of many methods that can be used to disinfect water.
In chemically pure water, molecular chlorine reacts with water and rapidly hydrolyzes to hypochlorous acid (HOCl) and hydrochloric acid (HCl): Both of the acids formed by hydrolysis react with alkalinity to reduce buffering capacity of water and lower pH. Every pound of chlorine gas added to water removes about 1.4 lb of alkalinity.
